World's Longest Immersed Tunnel Passes Milestone, But Faces Delays

August 03, 2026 — James Leggate - Engineering News-Record
Work on the $8-billion Fehmarnbelt Tunnel, which is planned to link Germany and Denmark as the world’s longest immersed tunnel, is progressing as crews achieved a milestone last month with the successful immersion of its first precast concrete element. But Danish state-owned project owner Femern A/S says the plan is now running at least two years behind schedule and the tunnel’s road and rail portions will open in two separate stages.

Bona Fide Dispute Defeats Violation of Prompt Payment Act

June 15, 2026 — David Adelstein - Florida Construction Legal Updates
Most, if not all, jurisdictions, including the federal government, have what is known as a “Prompt Payment Act.” The objective is to ensure prompt payment. If prompt payment is not made, the Prompt Payment Act provides for interest penalties, as well as potentially other costs such as attorney’s fees. But the thing is, it’s not as simple as untimely payment to support the recourse and interest penalties the applicable Prompt Payment Act affords. And the teeth associated with the applicable Prompt Payment Act are not as sharp as perhaps the party claiming untimely payment prefers. Read the full story...

USDOT’s DBE Interim Final Rule: How It Affects Current and Out-to-Bid DOT and Airport Projects

June 15, 2026 — Zachary F. Jacobson - The Construction Seyt
In our April 16, 2026 post, we discussed the U.S. Department of Transportation’s Interim Final Rule (IFR) concerning Disadvantaged Business Enterprise (DBE) and Airport Concession Disadvantaged Business Enterprise (ACDBE) certification, specifically as it concerns transportation and airport projects in California. This post addresses a broader question: What does the IFR mean for current and out-to-bid DOT projects operating under pre-existing DBE goals? The answer is that the IFR did more than change who qualifies as a DBE. It also changed how federally funded transportation and airport projects must be handled during the re-evaluation period. This affects active contracts, pending procurements, airport projects, design-build teams, and anyone relying on old assumptions about DBE goals and counting of DBE and ACDBE credit.

Construction Liens and the “Substantial Performance” Doctrine

April 08, 2026 — David Adelstein - Florida Construction Legal Updates
In a recent case dealing with a construction lien, the driving issue was whether the air conditioning contractor “substantially performed” before recording its construction lien against residential property. The importance here pertains to the substantial performance doctrine with respect to construction liens. The Third District Court of Appeal explained, with relevant citations, this doctrine as follows: Under Florida law, a contractor is entitled to a mechanic’s lien if he complies with all provisions of Chapter 713, governing construction liens, and “has substantially performed the contract.” Grant v. Wester, 679 So. 2d 1301, 1307 (Fla. 1st DCA 1996) (quotation omitted); Langley v. Knowles, 958 So. 2d 1149, 1151 (Fla. 5th DCA 2007) (“The substantial performance doctrine recognizes that a contactor who complies with all of the provisions of the contactor’s lien statute is entitled to enforce a lien if he has substantially, but not completely, performed his contractual obligations.”). Substantial performance is performance “so nearly equivalent to what was bargained for that it would be unreasonable to deny the promisee the full contract price subject to the promisor’s right to recover whatever damages may have been occasioned him by the promisee’s failure to render full performance.” Ocean Ridge Dev. Corp. v. Quality Plastering, Inc., 247 So. 2d 72, 75 (Fla. 4th DCA 1971). Read the full story...

The GKN Aerospace Chemical Release and the Laws Designed to Address It

July 06, 2026 — Sean M. Sherlock - Snell & Wilmer
On May 21, 2026, a 34,000-gallon storage tank at the GKN Aerospace facility in Garden Grove, California began leaking methyl methacrylate (MMA), a volatile and highly flammable industrial chemical used to manufacture high-strength acrylic plastics. GKN Aerospace makes advanced military and commercial transparencies, such as aircraft canopies, windshields, cabin windows, bullet-resistant glass, and spacecraft windows. In polymer chemistry lingo, MMA is known as a monomer. Monomers are like individual links to a chain. Under the right conditions they link up (react) with each other to form long-chained polymers, or plastics. MMA is an unstable monomer that requires controlled storage conditions to avoid setting off a polymerization (chain) reaction. According to early reports, the MMA tank at GKN Aerospace overheated. The cause of the overheating is not yet clear, but the overheating may have created conditions enabling the MMA to initiate polymerization, which in turn generated heat, which in turn generated pressure, activating the tank’s pressure-relief system and releasing MMA vapor into the atmosphere. Concerns about a runaway reaction, massive release, and explosion led the Orange County Fire Authority to order evacuation of approximately 40,000 residents and closure of thirteen schools.

Settlement Agreements and Contracts Require a Meeting of the Minds

July 20, 2026 — David Adelstein - Florida Construction Legal Updates
A settlement agreement does not need to be executed for it to be enforceable as long as there was a MEETING OF THE MINDS. The same rings true for any contract regardless of whether the contract is signed – THERE NEEDS TO BE A MEETING OF THE MINDS. In a recent case dealing with the settlement agreement on a construction lien, the essential settlement terms (money and mutual release) were memorialized in an e-mail exchange between the parties (owner and subcontractor). The settlement required the owner to pay the principal amount plus some attorney’s fees and then a mutual general release would be prepared. In response to the confirmatory email, the owner sent a check, which the subcontractor deposited, but the owner refused to sign the release signed and sent by the subcontractor. The owner further claimed it doesn’t need to pay the attorney’s fees because the lien amount was paid in full. The subcontractor sued arguing the owner breached the terms of the settlement. The appellate court agreed. Read the full story...
